MUX(1)MUX(1)NAMEmux - interactive television demo
SYNOPSIS
mux/mux
DESCRIPTION
Mux is a standalone application environment run from the Inferno con‐
sole in emu(1) or started automatically by init(8) in a native environ‐
ment. It directly uses the draw(3) device and either keyboard or
Infrared, and cannot be run under wm(1). It is included in this
release only as an example of the use of the Prefab graphics module
described by prefab-intro(2). The simpler style of graphics and inter‐
action provided by Prefab and demonstrated by mux might be more appro‐
priate than Tk on devices that use infrared remote control for interac‐
tion, such as televisions, or devices with limited screen space, such
as pocket devices or portable telephones.
Configuration
Mux produces a menu derived from the configuration file /ser‐
vices/basic. Each line in the file has three fields, separated by :,
of the following form:
icon:app:label
The icon is the name of a bitmap file to displayed in the menu along‐
side the textual label (which is the rest of the line). When the item
is selected, as described below, mux runs the Dis file
/dis/mux/app.dis
Applications
The following applications are available:
fnn Financial reports: a scrolling `ticker tape' along the bottom of
the screen.
movie Movies: select a film from a menu of categories
news Today's Newspaper: on-screen newspapers
tv Television
tvlist TV Timetable
